It will become an ion and no longer be neutral
<span> </span><span><span>Colored ions indicate the presence of a transition metal.
Transition metals display colors because of their incompletely filled d
orbitals. As the transition metal absorbs a particular wavelength of
light to raise the electron orbital, it causes the light that passes
through the solution to emit a color.</span></span>
I think the answer is D (number 4)
Valence election configuration is the electrons in the shell that equal to 8. it what forms chemcial bonds. Electron configuration is distribution of elections of an atom.
